Title: Improvements in or relating to cationic urea-formaldehyde resin and process therefor
IPC: C08G12/04
Filed: 1954-01-26
Abstract: A cationic polyalkylene-polyamine modified urea-formaldehyde resin for producing paper of improved wet strength is prepared by cooling to at least 10 DEG  C. an aqueous solution of the resin and separating the resulting precipitate.  The resin is prepared by reacting 1.90 to 2.10 moles of formaldehyde with 0.90 mol. of urea and modifying with 3 to 30 per cent by weight, based on the urea, of a polyalkylenepolyamine of the general formula H2N(CnH2nHN)xH, where n is 2 or more and x is 2 or more, e.g. diethylenetriamine, triethylenetetramine, tetraethylenepentamine, pentaethylenehexamine and the corresponding polypropylene and polybutylene polyamines.  The ingredients may be heated for a short time under alkaline conditions and then under acid conditions, or entirely under acid conditions until the required viscosity is obtained. Alternatively the urea and formaldehyde may be reacted under alkaline conditions followed by the addition of the nitrogen base and final reaction under acid conditions to the required viscosity.  In an example the resin solution was cooled by the addition of ice and a viscous gummy precipitate obtained.  After the separation of the resin by usual methods the filtrate may be concentrated and the urea-formaldehyde ratio adjusted, or paraformaldehyde, dimethylolurea or a concentrated formaldehyde solution added directly and then the ratio again adjusted and the modifier added.  Specification 663,736 is referred to.

Abstract: 424,855. Controlling variable-speed gearing. BONN, C. R. H., 56, Gibson Street, Hillhead, Glasgow. Jan. 24, 1934, No. 2442. [Class 80 (ii)] In variable - speed gearing in which the speed changes are effected through the agency of fluid supplied by a pump 32 driven from the driving-shaft 2 of the gearing, the pump 32 is adapted to be driven from the driven shaft, not shown, when the latter shaft overruns the former, as when a vehicle is coasting. Fast on the shaft 2 is the first element 33 of a train of gearing the last element 331 of which is connected to the shaft 22 of the pump 32 by a one-way clutch 4. This train is normally operative to drive the pump. A sleeve 66 geared to the driven shaft carries the first element 5 of a slower-driving train the last element 771 of which is connected to the pump shaft 22 by a one-way clutch 88. When the train 33, 331 ceases to drive, the train 5, 77<1> continues the drive so that fluid is kept available for effecting the speed changes. The application is described to an arrangement described also in Specifications 418,505 and 420,731, in which a pair of geared selector valves direct the pressure fluid selectively behind cone brakes which render operative different epicyclic trains.

[Also in Group XXXIII] A method of repairing a submerged submarine cable comprises bringing a " shaped " explosive charge into juxtaposition with it by means of a grapnel, exploding the charge to sever the cable, lifting the severed ends to the surface and jointing in a new length of cable. The " shaped " charge is of the type designed to propel a molten layer of metal in front of the generated gas pressure to act as a cutting agent, the cutting action being arranged substantially normal to the axis of the table. The grapnel consists of a flat metal plate 1 with a pair of prongs 5 affixed to each of its main surfaces, the prongs of each pair being spaced apart at their roots 4 and joined at their tips 6. The plate 1 has a rectangular slot between the roots of the prongs to contain the explosive charge. A further slot in the plate 1 accommodates a pick-up coil 11, and channels 16 and 18 accommodate the pick-up coil leads 17 and detonator leads (not shown). The grapnel is dragged transversely to the run of the cable to engage it in one of the pairs of prongs so that it will come to rest against the root of the prongs and hence against the explosive charge, an indication of this being given by the pick-up coil. Alternatively the grapnel may be adapted to take two explosive charges, means being provided to indicate which pair of prongs has engaged the cable.

Abstract: <PICT:0737118/III/1> <PICT:0737118/III/2> <PICT:0737118/III/3> <PICT:0737118/III/4> In a heat-exchanger (see Group XIII) for use in crystallizing, at least two hollow screw conveyer flights are mounted on rotatable shafts 55 in a casing which has a material inlet at or near one end and an outlet at or near the other, each flight being formed by a leading plate 41 and a trailing plate 43 connected together at or near their outer edges and connected at their inner edges to the shaft at a distance apart equal to 25-40 per cent of the pitch or of the average pitch if it varies, the flights overlapping to a distance at least 65 per cent of the height of each flight from shaft to outer edge.  Figures are given for the relative dimensions of the flights and of their spatial relationship.  The leading plate 41 is set at 85-95 degrees to the axis of the shaft 55.  A fluid such as steam, water, ammonia, dichlorodifluoromethane, diphenyl oxide or oil passes through the hollow flights and the shafts may also be hollow for the flow of this fluid, Fig. 6.  The treated material is moved through the casing as indicated by arrows in Fig. 5, and may be material to be crystallized or lubricating oil from which wax is to be extracted. In a double device the material passes from an upper to a lower casing to be returned to an outlet below the first inlet. The treating fluid may be introduced through openings 152, Fig. 6, in a disc which supports a duct 146 in the hollow shaft 55 and then flows into and through the flight to return through the shaft to discharge through the duct.  The treated material passes in the direction of the arrow 153.  Either or both of the flows of material and fluid may be reversed.  If there are two flighted shafts side-by-side they are of opposite hands and rotated in opposite directions.  There may be more than two shafts.  One shaft may be mounted above another with the flights of the same hand and rotated in the same direction, the axes being in a vertical or inclined plane.  A pair of shafts need not be parallel but may converge or diverge in the direction of material flow. The pitch of the flights may decrease towards the outlet.  Flat faces 41 of the flight may work against curved faces 43 as in Fig. 5 but like faces may work against one another.  The shafts, in section, are square, hexagonal or round.  Alternative flight sections are indicated in Figs. 14, 15.
